Detachable top lift for shoe heels



July 11, 1961 s. FREY DETACHABLE TOP LIFT FOR SHOE HEELS 2,991,565 DETACHABLE TOP LIFT FOR SHOE HEELS Simon Frey, 39 Zurcherstrasse, Oberengstringen, Zurich, Switzerland Filed Sept. 29, 1958, Ser. No. 763,942 Claims priority, application Switzerland Oct. 1, 1957 2 Claims. (CI. 3636) This invention relates to a novel and improved detachable cushion top lift for shoe heels.

An object of the invention is to provide a detachable cushion top lift of the kind indicated which does not impair the appearance of the heel to which it is affixed.

Another object of the invention is to provide a detachable cushion top lift of the kind indicated which can be affixed to the heel without appreciably weakening the latter.

Still another object of the invention is to provide a cushion top lift of the kind indicated which when worn out or damaged can be readily replaced by the user without special tools.

A further object of the invention is to provide a cushion top lift of the kind indicated which, although readily detachable, is securely held in place when affixed to the heel and which can be made of any suitable material and be transparent and/or colored.

An embodiment of the invention is described below with reference to the accompanying drawing in which:

FIG. 1 is a top plan view of a detached cushion top lift made according to the invention, and

FIG. 2 is a partial section along line IIII in FIG. 1 of a heel with the cushion top lift attached thereto.

The cushion top lift consists of a bottom portion 5 which has a contour coinciding with that of the bottom end portion of the heel body 1. A first projection 6 having a substantially round cross-section extends upwardly from the middle portion of the upper side of the top lift 5 and fits snugly into a corresponding recess in the heel body 1, as shown in FIG. 2.

A second projection 7 having a substantially rectangular cross-section extends upwardly from the upper side of the top lift 5 and fits snugly in a corresponding recess 8 in the heel body 1. The recess 3 extends forwardly to the front side of the heel body, as shown, and the second projection 7 has a front side which is flush ted States Patent 0 2,991,565 latented July 11, 1961 with the front side of the heel body 1. A shallow recess 9 is provided in the bottom side of the top lift 5 in order to enhance its grip on the ground.

The cushion top lift is made in one piece of vulcanized rubber or synthetic material. It may be transparent or colored, as desired. It eliminates the need for nails now commonly used to aflix rubber or leather discs to the heel bodies. This results in a longer life of the heel body since the nails every time make new holes in the heel body and thereby weaken it, particularly when used in heels of very small cross-section at the bottom end. When a top lift according to this invention is worn out, or nearly so, it is simply pulled out of the heel body and a new top lift is pushed into place by hand.

Modifications and variations of the embodiment described and shown will occur to a person skilled in the art, and the claims are drawn to cover all such legitimate modifications and variations.

What I claim as my invention and desire to secure by Letters Patent is:

1. A detachable cushion top lift for a heel body, comprising a base portion of a contour coinciding with that of the bottom portion of said heel body, a first projection having a substantially round horizontal cross-section extending upwardly from the top surface of said base portion and fitting snugly in a recess in the heel body, and a second projection extending upwardly from the top surface of said base portion in adjoining relationship with said first projection and fitting snugly in a recess in the heel body which extends to the contour of said heel body at one side thereof, whereby relative rotary displacement of said top lift and heel body about a vertical axis is positively prevented.

2. The detachable cushion top lift as set forth in claim 1, in which said second projection is substantially rectangular in horizontal cross-section.
